| dc.description.abstract | A system for measuring the through-focus point spread function (PSF) for intra-ocular lenses (IOLs) and converting to modulation transfer function (MTF) is developed. The system consists of a light source, eye model, IOL, magnifier, and CCD camera. By capturing the resulting image through a range of focus positions, the PSF is found and converted to MTF. The MTF displays differences in the depth of focus for monofocal, multifocal, and extended depth of focus (EDOF) IOLs. As multifocal and EDOF IOLs evolve, using the MTF to predict the image quality is vital to implanting the most appropriate lens in the patient's eyes. © 2022 SPIE. All rights reserved. | |
